The cause of carbon poisoning has been found, and there is a prevention plan, of course, there is some finishing work, which is not over, how to treat carbon poisoning after it, doctors must continue to study.

As for why charcoal can be transformed between poisonous and non-toxic because a handful of plant ashes can be transformed, the Taoist Waidan lineage, who is determined to pursue the path of material longevity, is very interested.

As for building chimney stoves and heating equipment, it is up to the public losers and the Mo family to do it.

"In the Warring States Period, the controversy of a hundred schools of thought was fascinating, but I think that today's affairs are discussed by a hundred schools, especially better than a hundred schools of thought, and the monarchs put aside their prejudices and let the knowledge of a hundred schools of thought gather together to solve the problems of the world. Li Shimin said with emotion.

"The old ministers have all been recorded in the book, and after they go back, they will definitely write today's events into the history books." Yan Shigu said solemnly.

All the sons and hundreds of schools of thought were immediately overjoyed, and said in unison: "This is the honor of the ministers.

Everyone got up, and the discussion of a hundred schools of thought officially ended.

Walking out of the conference room, breathing in the fresh air, everyone thought about the dangers of carbon poisoning, and suddenly felt emotional.

If it weren't for the solution of carbon poison today, if someone wanted to use this method to assassinate people, I am afraid that they would not know how to die.

"Brother Immortal Dao!" Cheng Yanjin leaned in front of the Immortal Daoist and said with a hippie smile, as if he didn't remember what he had just done with the Immortal Daoist.

"General Cheng has something to say!" The Immortal Daoist said helplessly.

"I don't know if there is any remaining secret hair dyeing technique of the Immortal Dao, the old man recently found that the gray hair has suddenly increased a lot, and it is really urging people to get old!" Cheng Yanjin looked at the immortal Daoist's black hair and said enviously.

In fact, Cheng Yanjin is not very old, but forty-five years old, although he is in the prime of life, he is the age when people's gray hair increases the fastest. The most sensitive.

The other people also couldn't help but tilt their ears sideways, most of them had experienced the Daomen Conference, and of course they knew that the hair of the eldest son was dyed.

Some time ago, it was rumored that the Emperor Taishang was nearly seventy years old, and his hair was all white.

Cheng Yanjin asked for it from Morton many times, but unfortunately Merton's inventory had already been scavenged by Li Yuan, and he was so annoyed that he had to push it to the Immortal Daoist.

Cheng Yanjin saw the eldest son today, how could he miss this opportunity, and immediately went up to fight to the death.

"Brother Immortal Dao, I also want to ask Brother Immortal Dao for a secret technique of dyeing hair, and I don't say whether I can cut my love." Surprisingly, Yan Shigu also stepped forward.

"Huh?"

Everyone immediately stared at Yan Shigu's white hair, this old man was the most old-fashioned, they didn't expect him to be as indecent as Cheng Biting Jin.

Yan Shigu smiled bitterly: "The old man is old, it doesn't matter if he has black hair or not, it's just that the old man's son Yan Chengyun has been white-headed since he was a child, so the old man has asked for medical advice and medicine, and even the two divine doctors are helpless. ”

"I see?" Everyone was stunned.

"Lack of whiteheads is indeed a problem for my doctors, and there is no effective treatment at present. Reiko's use of the secret technique of dyeing hair is indeed a good method. Sun Simiao praised.

"In this way, I'm afraid that my Mo Hospital will also have to ask Brother Changsheng Dao for some secret techniques for hair dyeing, so that if there are fewer whitehead patients to come, there will be a solution." Hua Yuan's heart moved.

The immortal Taoist was suddenly excited, and his secret hair dyeing technique was debunked by Merton at the Daomen Conference that day, which was simply pointed out by Wanfu, like a lost dog, who would have thought that it was Merton who saved him.

The secret technique of hair dyeing is so sought after, it must be a second spring for him, and this time, everything he does is beneficial to the world.

Changsheng Daoist Ji Shou said: "Don't worry, Poor Dao has cooperated with Mo Xiaoyou to entrust Mojia Village to produce hair dyeing secret techniques on his behalf, and mass production has begun at present, and it can be sold in Chang'an City in five days. ”

One of the reasons why he was sent out by the Taoist Waidan School is that the secret technique of hair dyeing is about to be released, and he has no experience in business, so he came to seek the cooperation of the Mo family this time.

"Thank you, Brother Immortal!"

Yan Shigu's face was overjoyed, and he hurriedly took a bottle.

Yan Cheng's young white head has been bothering him for a decade or two, and now he finally has a solution.

Cheng Yanjin also hurriedly took another bottle in his hand. The old face bloomed with a smile.

The people who listened to it were also happy in their hearts, and they could still afford to wait for five days.

With Li Shimin leaving, all the sons and hundreds of families dispersed.

In the study of Yan's house.

A gray-haired teenager was practicing calligraphy with a pencil, and his strokes were extremely serious.

The ancestor of the Yan family was Yan Hui, a disciple of Confucius, and Yan Shigu's grandfather was a famous Confucian Yan Zhitui, who wrote the famous Yan family motto.

Therefore, Yanfu's tutoring is very strict, even if no one supervises, this young man is still very self-disciplined.

A kind middle-aged woman came to the young man with a bowl of black sesame paste, and when she saw the young man's gray hair, she immediately felt distressed: "Carrier, don't waste your energy, take a rest!" ”

In this era, people don't know much about less whiteheads, and the most common belief is that they use their brains excessively.

Yan Chengcheng shook his head and said: "Mother don't worry, the child is just practicing calligraphy, and he doesn't bother his brain, and Doctor Sun said that the child is born with gray hair early, but it is born like this, not overusing the brain." ”

Yan Shi said distressedly: "That's not in a hurry, come, drink this bowl of black sesame paste, according to folk remedies, many people have drunk black sesame paste, cured less whiteheads." ”

Yan Chengyun smiled helplessly, he didn't know how much he drank this black sesame paste, but it didn't have any effect at all.

However, Rao is like this, Yan Chengyun did not live up to his mother's expectations, obediently picked up the black sesame paste and drank it.

"Ahem!" Yan Shigu coughed heavily and walked into the study.

"Sir!"

"Father!"

Yan and Yan Cheng run etiquette, and in the Yan family motto, husband and wife and father and son still have to abide by etiquette.

Yan Shigu nodded and said, "This is the content of today's discussion of a hundred schools, you can sort it out first, and learn the wisdom of each predecessor by the way." ”

"A hundred schools of thought?" Yan Chengyun's eyes lit up, and he asked, "The Mo family is also among them?" ”

Mo Jiazi is now the idol of all teenagers in Chang'an City, even Yan Chengyun is no exception.

"Carbon poison, chimneys, heating ......"

"Everywhere is knowledge, and the practice of human feelings is the article!"

Yan Chengyun picked up his father's shorthand notes, his eyes became brighter and brighter, the collision of hundreds of schools of thought, and Merton's classic poems, all of which made him fascinated.

"Also, this is the secret technique of dyeing the hair of the Immortal Daoist, when you finish tidying up, dye your hair black!" Yan Shigu put a bottle of ointment on the table, pretended to be nothing, and walked out of the study.

Soon, in the study, there were screams of surprise from Yan Cheng and Yan's family, and the strict tutors were all left behind at this moment.

After all, Yan Chengyun is a teenager, with gray hair all day long, he has endured the fingers of others and the cynicism of his peers, and with the secret technique of dyeing his hair, these things will never happen again.
